> Keep your oxidative stress low and you will not get heart disease.

I think we should always be careful when we speak in absolutes. The conclusion from the article:

> This result suggests that oxidative stress may be a determinant of [C-reactive protein] levels and promote pro-atherosclerotic inflammatory processes at the earliest stages of [coronary heart disease] development.

I'm not saying the result is wrong, but I am saying "if you A you will not get B" is over-promising.

> Keep your oxidative stress low and you will not get heart disease.

if you take this advice literally, you should stop exercising

Yes, you are correct. Nothing wrong with walking, helps keep weight low and fat cells are a huge source of oxidative stress. Better to eat low calorie, high nutrient dense foods.

Easier said than done. Even microplastics have been liked to oxidative stress and inflammation.
